Easy fix (would have been easier to cut before it was all back together. Removed the wheels and got a better look. Dropped the tie rod end and cut a little square. Still had to wedge a screw driver to get it off the rubber when it was back together. I like this better than running without the shield

Yeah, I would say this is the easiest fix. I assume some good tin snips or a dremel/grinder will make quick work of it.
How did you do this? Heard of this a few times but I am not really sure. As in germany it is generally not allowed to go smaller rotors using the standard 340mm rotors on my 335i is not possible. 340 calipers are way cheaper tho. That is why I would be interested in running the 340 calipers on the standard 348mm rotors.
끝났어!
Thank you for the posting
The bottom line is, if you only have an e60 disk and an eccentric bushing,
You mean you can fit the caliper without processing it?
Hi, first thanks for the great threat and all the info.
I have already installed the fronts on my E93 along with M3 master, just about to do the rears and at the point of pressing in my new bushing inserts.
Mine look a bit more offset than the ones I've seen in the thread, they look real thin at the edge. Are these ok to use?
Also found an easy way to pull the old bushings out, 30mm socket with a long bolt that threads into the caliper and a washer, I used an old bolt from some previous suspension work.

Hey guys, hoping to get some advice.
I tried to install the rear calipers with what I thought were E60 zimmermann rotors, but once installed I noticed that the rotor wasn't sitting in the centre of the caliper and the back face of the rotor was actually touching the caliper, which also stopped it from spinning.
I'll attach some pics, there is 0mm clearance on the back face and around 6mm on the front.
I found a part number on the rotors I have which is BDC5652 and found they are made by Quinton Hazell, apparently they are 67mm in height and not 63mm like the zimmermanns which is probably why they are sitting further back. They are almost new rotors, still showing 24.10mm on my cheap vernier caliper, although measuring the height I got 65mm not 67mm. It would still make sense that the 63mm zimmermann would sit at least 2mm further forward though, resulting in 2mm clearance at the back and 4mm at the front.
I also found an OEM number for them which is 34216864046 which realoem shows is for E65 only.
So I clearly have the wrong discs, however as they are almost new would it be possible to use a 2-3mm spacer between the hub and disc to centre it, or would I need to mill the inside of the caliper if I wanted to use them? In the case of having to mill them then I'd just get zimmermann replacements instead.
I figure the spacers would be cheaper than rotors and also avoid wasting two almost new rotors, however if the spacers aren't a particularly safe option then I wouldn't want to use them. Could it cause a problem with the handbrake?
Thanks for any advice

Can't give any advice on the eccentric Bush, will just have to see if it lines up I guess, perhaps take some measurements before pressing it in.
Regarding the disc's, that's tough luck. Who knows if Zimmerman even makes those blanks anymore? It's been so long. Sorry I can't be much help here, a lot of this has gone out of my head already.

Your rotors mount hub-centric, so a 3mm spacer between the hub face and back of rotor face is not going to work well, most likely. If you go to zimmerman.de you can get all the measurements for each rotor, including the backspacing.
Back in 2020 when I originally heard of this upgrade I wrote it off as I thought it would mean a mandatory upgrade to 19" wheels. I plan on eventually doing so, but I have also heard reports that some 18" wheels clear. Is this true?
I see people have reported that the 19" M-Sport Premium 225s fit but can anyone vouch if M-Sport Style 193 stockers clear? I don't want to be locked out of my stock wheel if I plan on going this route but the Blue calipers on Space Grey... hnnnnng
very... curious......

This might be the most damning piece of evidence I need to make my conclusion. The offsets on these wheels are nearly 20mm higher than stock 193s. May be the smallest wheels I've seen stretched around this upgrade. However I am still worried about the spoke design rubbing on the caliper face.
Has anyone flat out bolted stock 193s onto the MPerformance BBK without issues?
From what I understand when I was doing research, the barrel design of 18” E-series wheels really restrict you on what would fit. That’s why I had to switch to an F-series design for my winter set. My stock 18” style 261M’s would have not cleared.
Hope you can find someone who tested the 193’s with this bbk. If they don’t fit, go to the f30 realoem page below for the retrofit and it lists OEM wheels that work. I did a similar thing but with the f22 since the e82 shares similar offsets to it. I was able to directly swap the tires from my old set onto them

The RealOEM page only lists 3 colors as being the M Performance brakes (Red, Yellow, Orange)
Does that mean that the F30 Blues are not M Performance brakes (370/380mm)? Only the F80 Blues are "BBK"? I am seeing a few members installing BMW Blue on their rides...

I have the 370/380 blue version from euro 330d so it’s not an exclusive colour to the f80. I believe they were blue if it was factory installed and the red/orange/yellow applies to dealer installed
